Abstract (en)
[origin: EP0572288A1] The subject of the present invention is the use, in a detergent composition, of an alkali metal amorphous silicoaluminate as agents for capturing calcium-containing precipitates. The invention also relates to a detergent composition comprising at least one alkali metal amorphous silicoaluminate, alkali metal carbonate, the alkali metal is preferably sodium, and at least one inhibitor of calcium carbonate crystalline growth, the alkali metal carbonate being present especially as the main agent for removing ionic calcium.
